| 摘 要： | 研究了碳纤维布约束混凝土方柱的轴向抗压性能，考虑了纤维布的粘贴方式、纤维布数量以及纤维布条之间的间距对约束效果的影响。重点分析了其破坏形态、承载力和轴向压应力与应变的关系，结果表明碳纤维布约束混凝土柱可不同程度地提高其抗压承载力和变形能力；整体加固效果明显优于条带加固；随加固率的增大，峰值应力、峰值应变、极限应力和极限应变都有所提高，轴向应力应变曲线的下降段趋于平缓。

| Abstract: | Axial compression resistance performance of concrete square-columns confined by carbon fiber reinforced polymer(CFRP) sheets under axial compression was studied,with consideration of mayor factors affecting confinement of concrete such as: affix methods,amounts of CFRP,and space between fiber strips.The study focused on analysis of failure configuration,bearing capacity,axial stress-strain curve.The results showed that axial compressive strength and deformability are improved efficiently by using CFRP to st... |
